With the advent of advanced artificial intelligences and the machine-designing machines, scientific discoveries accelerated in ways humanity could hardly control or forecast. Although no A.I singularity (a self-improving machine so advanced so as to be incomprehensible to humans) was witnessed, technology made tremendous advances in several fields. Physics, genetics, computer sciences discovered new realms and shook the very foundations of humanity.Almost limitless energy, transhumanism and man-machine fusion became realities. Humans, almost of them by now interfaced with computers, began to spread across the solar system -the Tsiolkovskian "cradle" was left for good. It was during that tremendous expansion that humanity came to find what was to become the Gate.

WORMHOLE GATES.In the year 2163 A wormhole was discovered on the outskirts of the asteroid belt in the solar system. It was stable, but it tended to move around within a given radius of 100 billion kilometres. After years of study and construction a wormhole Stabilizer was created and fixed to the wormhole. Taming it like a wild beast to one point in place. Scientist believed that that the other end of the wormhole was connect the the nearest solar system, Proxima Century. Humanity had created their first Wormhole gate. It allowed humanity to travel to Proxima Century. A huge construction vessel went through and built another stabilizer on the other end, connecting the two solar systems together in a stable manner. This was the golden era human space travel. Other wormholes were found that connected to other systems. and so on. Humanity started to plant their footprint in every solar system within its reach.
